+# Django Enhanced API Docs
+
+Enhanced API documentation for Django REST Framework using drf-spectacular with custom schema generation, automatic parameter descriptions, and code samples.
+
+## Features
+
+- **Optional API Documentation**: Enable/disable API docs via environment variable
+- **Enhanced Schema Generation**: Automatic parameter descriptions for filters, search, ordering, and pagination
+- **Language Support**: Built-in support for translatable fields with language parameter
+- **Code Samples**: Automatic cURL code sample generation for all endpoints
+- **Custom Tags**: Organize endpoints with custom tags mapped to ViewSet classes
+- **Comprehensive Error Responses**: Automatic addition of standard HTTP error responses
+- **Pagination Examples**: Dynamic pagination URL examples based on actual endpoints
+
+## Installation
+
+### Via pip (when published)
+
+```bash
+pip install django-enhanced-apidocs
+```
+
+### Via Git (development)
+
+```bash
+pip install git+https://github.com/yourusername/django-enhanced-apidocs.git
+```
+
+### As Git Submodule (development)
+
+```bash
+cd your-django-project
+git submodule add https://github.com/yourusername/django-enhanced-apidocs.git
+pip install -e ./django-enhanced-apidocs
+```
+
+### Editable Installation (local development)
+
+```bash
+pip install -e /path/to/django-enhanced-apidocs
+```
+
+## Configuration
+
+### 1. Add to INSTALLED_APPS
+
+Add the following to your Django `settings.py`:
+
+```python
+# Enable API documentation (default: enabled in DEBUG mode)
+ENABLE_API_DOCS = os.environ.get('ENABLE_API_DOCS', str(DEBUG)).lower() in ('true', '1', 'yes')
+
+INSTALLED_APPS = [
+    # ... your other apps
+]
+
+# Conditionally add API documentation
+if ENABLE_API_DOCS:
+    INSTALLED_APPS.extend(['drf_spectacular', 'django_enhanced_apidocs'])
+```
+
+### 2. Configure REST Framework
+
+```python
+REST_FRAMEWORK = {
+    'DEFAULT_AUTHENTICATION_CLASSES': [
+        'rest_framework.authentication.BasicAuthentication',
+        'rest_framework.authentication.SessionAuthentication',
+    ],
+    'DEFAULT_PERMISSION_CLASSES': [
+        'rest_framework.permissions.IsAuthenticated',
+    ],
+    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
+    'PAGE_SIZE': 20,
+}
+
+# Set schema class when API docs are enabled
+if ENABLE_API_DOCS:
+    REST_FRAMEWORK['DEFAULT_SCHEMA_CLASS'] = 'django_enhanced_apidocs.schema.CustomAutoSchema'
+```
+
+### 3. Import Spectacular Settings
+
+```python
+# In settings.py
+if ENABLE_API_DOCS:
+    from django_enhanced_apidocs.conf import get_spectacular_settings
+
+    # Pass your dotenv config dict
+    SPECTACULAR_SETTINGS = get_spectacular_settings(config)
+```
+
+The `config` parameter should be a dictionary with at least:
+- `LOCAL_SWAGGER_HOST` (optional): Server URL for API documentation (default: 'http://localhost:8000')
+
+You can also override settings after import:
+
+```python
+if ENABLE_API_DOCS:
+    from django_enhanced_apidocs.conf import get_spectacular_settings
+
+    SPECTACULAR_SETTINGS = get_spectacular_settings(config)
+
+    # Customize settings
+    SPECTACULAR_SETTINGS['TITLE'] = 'My API'
+    SPECTACULAR_SETTINGS['DESCRIPTION'] = 'My API Description'
+    SPECTACULAR_SETTINGS['VERSION'] = '2.0.0'
+    SPECTACULAR_SETTINGS['CONTACT'] = {'email': 'api@example.com'}
+```
+
+### 4. Include URLs
+
+Add documentation URLs to your `urls.py`:
+
+```python
+from django.urls import path, include
+from django.conf import settings
+
+urlpatterns = [
+    # Your API endpoints
+    path('api/v1/', include('your_app.urls')),
+]
+
+# Conditionally include API documentation URLs
+if getattr(settings, 'ENABLE_API_DOCS', False):
+    urlpatterns.append(path('', include('django_enhanced_apidocs.urls')))
+```
+
+This adds the following endpoints:
+- `/swagger/` - Swagger UI
+- `/redoc/` - ReDoc UI
+- `/api/schema/` - OpenAPI JSON schema
+
+## Environment Variables
+
+Control API documentation via environment variables:
+
+```bash
+# Enable API docs (default: true in DEBUG mode)
+ENABLE_API_DOCS=true
+
+# Set custom server URL for API docs
+LOCAL_SWAGGER_HOST=http://localhost:8000
+```
+
+Or in your `.env` file:
+
+```
+ENABLE_API_DOCS=false  # Disable in production
+LOCAL_SWAGGER_HOST=https://api.example.com
+```
+
+## Custom Tags Configuration
+
+The package comes with pre-configured tags for common Django apps. You can customize them in your settings:
+
+```python
+if ENABLE_API_DOCS:
+    from django_enhanced_apidocs.conf import get_spectacular_settings
+
+    SPECTACULAR_SETTINGS = get_spectacular_settings(config)
+
+    # Add custom tags
+    SPECTACULAR_SETTINGS['TAGS'] = [
+        {
+            'name': 'Products',
+            'description': 'Product management endpoints',
+            'viewsets': ['ProductViewSet', 'ProductVersionViewSet']
+        },
+        {
+            'name': 'Users',
+            'description': 'User management endpoints',
+            'viewsets': ['UserViewSet']
+        },
+    ]
+```
+
+## Features in Detail
+
+### Automatic Parameter Descriptions
+
+The package automatically enhances query parameters with human-readable descriptions:
+
+- **Search**: Describes which fields are searched
+- **Ordering**: Explains ascending/descending syntax
+- **Pagination**: Documents page number format
+- **Filters**: Generates descriptions based on field types (boolean, integer, foreign key, etc.)
+
+### Language Parameter
+
+For projects using translatable fields (e.g., `django-translatable-fields`), the package automatically adds a `lang` parameter to GET endpoints:
+
+```
+?lang=en  # Returns English translations
+?lang=de  # Returns German translations
+?lang=fr  # Returns French translations
+```
+
+### Automatic cURL Code Samples
+
+Every endpoint includes a ready-to-use cURL command with:
+- Correct HTTP method
+- Authentication headers
+- Request body (for POST/PUT/PATCH)
+- Sample data based on serializer schema
+
+### Standard Error Responses
+
+All endpoints automatically document standard HTTP error responses:
+- 400 Bad Request
+- 401 Unauthorized
+- 403 Forbidden
+- 404 Not Found
+- 409 Conflict
+- 500 Internal Server Error
+
+## Usage Example
+
+After installation, access your API documentation at:
+
+- **Swagger UI**: http://localhost:8000/swagger/
+- **ReDoc**: http://localhost:8000/redoc/
+- **OpenAPI Schema**: http://localhost:8000/api/schema/
+
+## Disabling in Production
+
+To disable API documentation in production:
+
+```bash
+# In your production .env file
+ENABLE_API_DOCS=false
+```
+
+Or in your settings:
+
+```python
+ENABLE_API_DOCS = False
+```
+
+When disabled:
+- `/swagger/`, `/redoc/`, `/api/schema/` return 404
+- `drf_spectacular` and `django_enhanced_apidocs` are not loaded
+- No performance impact on API endpoints
+
+## Requirements
+
+- Python >= 3.9
+- Django >= 4.0
+- djangorestframework >= 3.14
+- drf-spectacular >= 0.26
